Milk Thistle Extract

Milk thistle is an herbal remedy derived from the milk thistle plant, also known as Silybum marianum.

This prickly plant has distinctive purple flowers and white veins, which traditional stories say were caused by a drop of the Virgin Mary’s milk falling onto its leaves.

The active ingredients in milk thistle are a group of plant compounds collectively known as silymarin (1Trusted Source).

Its herbal remedy is known as milk thistle extract. Milk thistle extract has a high amount of silymarin (between 65–80%) that has been concentrated from the milk thistle plant.

The silymarin extracted from milk thistle is known to have antioxidant, antiviral and anti-inflammatory properties (2Trusted Source, 3Trusted Source, 4Trusted Source).

In fact, it has traditionally been used to treat liver and gallbladder disorders, promote breast milk production, prevent and treat cancer and even protect the liver from snake bites, alcohol and other environmental poisons.
